Honored ContributorHow to improve compilation process on Quartus II Web Edition
Dear sirs. First of all, thank you for your time.
I am using Quartus II Web Edition 15.0 and the time of compilation it is about 3 minutes with a simple code example. I am using Windows 7 (64 bits) on a PC with 8G RAM and AMD A8 5500B APU processor. This compilation time it is normal for this configuration or it is possible to improve. Thanks Fabio Bairros4 Replies
Altera_ForumGet more RAM. However, 3 minutes is already quick - you're clearly compiling a small design. Compile times for larger designs in large devices will take hours. Then it's worth putting in some effort to reduce compilation time.

At least 16GB or preferably 32GB of DRAM (to act as disk buffer storage). A fast SSD or PCIE disk will also make a big difference.
I have a Win7 64b XEON with 8 cores (altho the web edition does not use more than 2 cores IIRC) and 64GB of DRAM and a 1GB hybrid flash / magnetic disk. On a reasonably complex Cyclone IV design under web 16.0 it takes 2:35 start of compile to end of bit config file generation. - Altera_Forum
3 minutes! I envy you.
12 core Xeon, 128GB ram takes 6 hours for a stratix 4 (that has many clock domains and is very full). Ram is the biggest bottleneck. Then CPUs and hard disk. Sometimes you just have to wait! - Altera_Forum
Interesting doc to read (for v15, but probably still applies to v16): https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/rn/rn_qts_dev_support.pdf
How much host memory is recommended for various target FPGA devices.
